ABSTRACT:
Vehicular optical radar apparatus adapted to enhance actual operating efficiency in causing emitted light to continuously scan in a horizontal direction with a diffusing-angle setting device (44) for setting a diffusion angle (.alpha.) to be used for diffusing the emitted light in a vertical direction. This vehicular optical radar apparatus further comprises light receiving devices (60 to 90) that is held in such a manner as to be placed at a horizontally predetermined relative position and that is used to receive reflected light (L2) from an object, a distance computing device for computing a distance from the vehicle to the object according to a delay time between a moment, at which the emitted light is generated, and a moment at which the reflected light is received, and a direction detecting device for detecting a direction of the object according to a direction in which the emitted light is outputted when the reflected light is obtained. In this apparatus, the horizontal scanning device includes an optical system employing a prism and is operative to cause a luminous flux of the emitted light to scan continuously in a horizontal direction by transmitting and refracting the emitted light by means of the prism while rotating the prism.
